how much are you willing to pay? I'm sure a number of people on here would be willing to sell theirs if you offered them enough money, otherwise Ebay and Craigslist and local news paper ads seem to be the best bet.
I would suggest trying to get one with as straight a body and paint as possible. Body work tends to be really pricely even when compared to engine work, electrical, AC, etc.
As an example, in SoCal to paint a VX that has a number of door dings at a respectable autobody shop is typically around $2.5K!! A little labor could be saved if you remove all of the lights, door locks, etc. yourself.
On a side note - Even if you don't like white cars, white tends to hold up the best over the long haul.
